Finally got a chance to fit one if these Tecnigas exhausts to a GTS300 fits gts250 as well , after the normal struggle of getting the old exhaust off (these come with a full down pipe in stainless not just a slip on can) found the new one quite an easy fit, road legal, only slighter louder than the standard and a lot lighter. Dyno graph show before and after,there was a slight gain on Bhp but no rollers had to be changed just a new belt which gave it a bit more gearing to hit the rev limiter at 82mph. So a nice light stainless and Ali full exhaust system that can just be bolted on.
